Abstract

The invention relates to a method for producing a zigzag-folded nonwoven material for a filter, wherein the nonwoven material is produced by a melt-spinning process, the method comprising the following work steps: folding the nonwoven material by means of a folding device, wherein a large number of folds results, wherein the folds divide the nonwoven material into first limbs and second limbs, such that the nonwoven material is zigzag-folded; and subsequently welding a weld region of the first limb of a fold to at least one weld region of the second limb of a fold by means of a thermal-contact welding process, wherein a welded joint is formed between the two mutually facing sides of the limbs of a fold. The invention also relates to a corresponding device and a corresponding nonwoven material.
